What Is Ramipril and What Is It Used For?

Ramipril is a medicine that belongs to a class of medications called ACE inhibitors (Angiotensin-Converting Enzyme inhibitors) . There are quite a few answers to the question “What is Ramipril medication used for ?” Its primarily used to treat key cardiovascular and kidney related conditions.

Rampiril works by relaxing blood vessels, lowering pressure in the body’s system and makes it easier for the heart to pump blood. Ramipril’s mechanism of action involves blocking the enzyme that produces a hormone called angiotensin II which causes the blood vessel to narrow. 

Ramipril is used in the treatment of conditions such as:

  • Hypertension -Ramipril can help lower blood pressure and reduce the risk of complications like heart attack or stroke (as seen in image 1). 
  • Heart Failure – Rampril can help improve heart function in people with heart failure, especially after a heart attack
  • Post-Heart attack recovery – Ramipril can help improve recovery outcomes for people who have just suffered a heart attack. 
  • Chronic Kidney Disease – Ramipril slows the progression of kidney disease in people who suffer from conditions like diabetes or hypertension by reducing pressure on the kidneys

Ramipril is taken as an oral tablet once or twice a day depending on the prescription and recommendation by doctor.

How Does Ramipril Work in the Body?

Ramipril works by targeting a hormone cascade in the body known as the Renin Angiotensin Aldosterone System (RAAS). The RAAS System normally plays a critical role in regulating blood pressure, fluid balance and the health of the blood vessel. 

Ramipril is an ACE inhibitor (Angiotensin Converting Enzyme Inhibitor) that works by blocking the enzyme (ACE) which converts Angiotensin I to Angiotensin II. Angiotensin II has 2 primary functions:

  • Causes constriction of the blood vessels
  • Stimulates the release of aldosterone which causes retention of water and salt 

By blocking ACEi, Ramipril helps reduce the workload on the heart and also widens blood vessels to ease circulation of organ rich blood to the organs of the body like the heart, kidney and  liver.

Ramipril used for hypertension also helps to relax the blood vessels supplying the kidneys and thereby reduces strain on the kidneys and prevents damage, especially in conditions like diabetes or chronic kidney disease. 

Ramipril Dosage Guidelines

The dosing guidelines and dose ranges for Ramipril depends on factors like the condition being treated, your individual medical history and how you respond to medicines. Different conditions have different dose ranges, maximum recommended doses and ramipril dosage side effects

Normal Dose of Ramipril for Adults

The normal dose  of Ramipril depends on the condition being treated, the patient’s medical history and how they respond to medicine. The following are some typical dosing guidelines for some common conditions:

  • Hypertension:
    • Starting dose of 2.5mg once daily
    • Maintenance (steady) dose of 2.5mg-10mg per day either as a single dose or divided into two
  • Heart Failure (Post Heart Attack)
    • Starting dose of 2.5mg or 1.25mg twice daily (please speak to your healthcare provider about which one is appropriate for you)
    • Maintenance dose: 5mg twice daily (as your healthcare provider prescribes)
  • Prophylactic for high-risk patients
    • Starting dose of 2.5mg once daily
    • Maintenance dose which is gradually increased to 10mg (taken at once or split in two as directed by your healthcare provider)
  • For Kidney protection
    • Starting dose of 1.25mg -2.5mg once daily
    • Maintenance dose of upto 5-10mg a day depending on kidney function and tolerance 

Maximum Dose of Ramipril

You maybe asking “what is the highest dose of Ramipril you can take ?” Well the answer to this question is that the maximum dose for ramipril is typically 20mg a day but this can vary depending on the condition you are treating. For conditions like hypertension (high blood pressure), it is typically 20mg. However for conditions like post-heart attack, prophylactic for high-risk patients or for chronic kidney disease, the maximum dose is 10mg. This Ramipril highest dose can be taken as a single dose or split into two over the day, please speak to your healthcare provider about which option is best for you. Please don’t take higher than the recommended maximum doses of Ramipril, as taking medicines above this ramipril dose range can be a ramipril overdose amount and lead to an overdose. 

Ramipril Dosage for High Blood Pressure

The typical starting Ramipril dosage for high blood pressure is 2.5mg once daily, however this is steadily increased to a maintenance dose of 2.5-10mg per day either as a single dose or divided into two. 

The exact dosage will depending on factors such as your tolerance, individual health and individual response. 

The maximum ramipril dose for high blood pressure is 20mg daily, however this can also be taken at once or split into two. 

Please speak to your healthcare provider about which dose of ramipril is right for you treating your high blood pressure. 

What Should You Do If You Miss a Dose?

Missing a single dose is not usually harmful but missing multiple doses cam impact blood pressure control

If you are unsure about how regular you have been with your doses, please consult your doctor or pharmacist. 

What Happens If You Overdose on Ramipril?

Overdosing on Ramipril can cause serious side effects such as:

  • Severely low blood pressure (hypotension) leading to syncope, dizziness and fainting
  • Very fast heart rate (tachycardia) or Very Slow Heart Rate (Bradycardia)
  • Kidney failure leading to a reduced urine output
  • Breathing difficulties
  • Confusion or extreme fatigue 

If someone overdoses on Ramipril,  Lay the person flat on their back especially if they feel faint or dizzy and call emergency services (911 or applicable local number) as soon as possible. 

How to Take Ramipril Effectively

When Is the Best Time to Take Ramipril?

You should aim to take Ramipril at the same time each day, with or without food 

It may be best to take it in the morning to help you establish a routine with your medicine

How Long Does Ramipril Take to Work?

Ramipril starts working within a few hours of you taking it, however it’s full effects begin to be seen within 1-2 hours of taking a dose. The peak blood pressure lowering effect can be seen 3-6 hours after taking your dose. Full benefit of taking the medicine comes from regular use over 2-4 weeks to help with blood pressure control. 

How Long Does Ramipril Stay in Your System?

The time Ramipril stays in your system depends on its half-life, metabolism and elimination process. 

The active metabolite in Ramipril has a half-life of 13-17 hours, allowing it to maintain its blood pressure lowering effects for 24 hours and be effective with the once daily dosing schedule. 

It takes around 5-7 days for the body systems (kidneys and liver) to excrete the ramipril compound from the body after you stop taking it. However these are mostly inactive metabolites that are being excreted. 

Side Effects of Ramipril

Ramipril is generally a well tolerated drug however you may be asking: “What are the side effects of Ramipril ?” Ramipril, like most medications, has a few side effects (as illustrated in picture 2).  Most side effects are mild and occur particularly when first taking the drug, these usually improve over time. Some are rarer and more serious however and its advisable to watch out for these and seek medical attention immediately if they occur. 

Common Side Effects of Ramipril

Ramipril is generally a well tolerated drug but it can cause some side effects, especially when one first starts taking it.  Most blood pressure tablet ramipril side effects are mild and improve over time. The most common side effects include:

  • Dry persistent cough
  • Dizziness or lightheadedness
  • Fatigue or muscle weakness
  • Headache
  • Nausea or vomiting
  • stomach pain or indigestion
  • Low blood pressure (hypotension)

Long-Term Side Effects

Long term side effects of Ramipril include:

  • Worsening kidney function
  • Chronically High Potassium Levels (Hyperkalemia) which can cause muscle weakness and heart rate irregularities
  • Persistent , dry, irritating cough 
  • Over a long time of use, the blood pressure can also run the risk of becoming too low (hypotension). 
  • Long term use can also cause persistent fatigue, possibly due to lower blood pressure and electrolyte imbalances. 

Severe Side Effects to Watch Out For

Serious but rare side effects include:

  • Severe allergic reaction leading to swelling of the lips, tongue, face or throat- which can be life threatening
  • Severe dizziness or fainting due to low blood pressure
  • Kidney problems leading to reduced urine output, swelling or confusion
  • Liver problems that can lead to jaundice
  • Very high potassium levels that can cause muscle weakness, irregular heartbeats or palpitations 

What to Do If You Experience Side Effects?

For mild and common side effects – it is best to wait and watch as the body usually adjusts

If the persistent cough is bothersome – it is best to speak to your doctor about switching Ramipril for another blood pressure medication

If you experience severe reactions, seek medical attention immediately, especially if you experience swelling, difficulty breathing or severe dizziness.

 Foods, Drinks, and Medications to Avoid With Ramipril

Certain foods and drinks can interact with Ramipril and improve/lower its effectiveness or increase risk of side effects. 

Alcohol and Ramipril

Taking Alcohol with Ramipril can increase dizziness and lightheadedness, especially when standing up. It can exacerbate the low blood pressure side effects of taking ramipril. Limit alcohol intake while taking Ramipril or stop drinking alcohol  if you feel unwell after drinking. 

Coffee and Ramipril

Caffeinated drinks like Coffee can raise blood pressure and may counteract the effects of blood pressure medication such as Ramipril.

Foods to Avoid While Taking Ramipril

Foods to avoid while taking Ramipril include foods that are especially high in potassium as Ramipril already raises blood potassium levels. Pairing it with foods high in potassium can lead to muscle weakness or irregular heartbeat. Some of these foods include:

  • Bananas
  • Potatoes
  • Oranges or Orange juice
  • Spinach and leafy green vegetables 

Drug Interactions With Ramipril

There are certain medications to avoid taking when you are on Ramipril, some of these include:

  • Other blood pressure medications such as Diuretics (Water Pills), other ACE inhibitors (Lisinopril, Enalapril) or other hypertensives like Losartan or Valsartan
  • Non Steroidal Anti-Inflammatory drugs such as Ibuprofen, Naproxen or Diclofenac
  • Potassium supplements or salt substitutes that can dangerously raise potassium levels and cause heart problems
  • Lithium as Ramipril can increase it’s levels in the body and cause toxicity

Please speak to your healthcare advisor about the medications you are currently on and if you have any concerns about drug interactions with Ramipri. 

Alternatives to Ramipril

There are several other medications that can be used as alternatives to Ramipril to treat conditions like high blood pressure, heart failure and kidney protection. Some of these options include:

  • Other ACE inhibitors (Similar Mechanism of action to Ramipril)
    • Lisinopril – a common alternative with a longer duration of action
    • Enalapril – shorter acting, often taken twice daily
    • Perindopril – used for heart and kidney protection 
  • Angiotensin Receptor Blockers (ARBs) 
    • ARB’s are a good option to ACE inhibitors like Ramipril, especially if it causes a dry cough. ARB’s work by blocking the action of the hormone angiotensin on blood vessels, allowing them to dilate and lower blood pressure. Options include:
      • Losartan – a popular and well tolerated alternative 
      • Valsartan- good for heart failure and kidney protection 
      • Candesartan – Long acting ARB option 
  • Calcium channel blockers – If ACE inhibitors or ARB’s are not suitable 
    • Uses of tablets of Calcium Channel Blockers  relax the blood vessels but do not affect kidney function, options include:
      • Amlodipine – particularly common choice in older patients
      • Felodipine – longer acting alternative
      • Diltizaem/Verapamil – affect muscle cells in the heart and cause slow beating 
  • Beta Blockers – for heart conditions and high blood pressure
    • These medications may be used as alternatives to Ramipril to be used post-heart attack to assist with heart failure or hypertension. Options include:
      • Bisoprolol – commonly used for heart failure
      • Metoprolol – Used for high blood pressure and heart conditions 
      • Carvedilol – helps in heart failure 

The option that you choose as an alternative to Ramipril depends on factors like your condition and what Ramipril tablets are for, your individual response and any side effects you display. Please speak to your healthcare advisor about alternative options to Ramipril that may suit you best.
